Everton have held more negotiations with Rafa Benitez about becoming their new manager as a backup plan when Nuno Esprito Santo's chase halted.
Everton owner Farhad Moshiri made Santo a written offer last weekend after the Iranian determined the former Wolves manager was the man he wanted to succeed Carlo Ancelotti.
Everton had hoped to announce Nuno by the end of the week, but the issue has not progressed as rapidly as expected, leaving the door open for ex-Liverpool manager Benitez.
Moshiri talked with Benitez early last week, but there has been additional contact since then as he seeks backup plans in case the long quest to get Nuno fails.
The 47-year-old appeared to be on his way to Crystal Palace earlier this month, only for the Eagles to call off their chase due to a breakdown in negotiations.
Moshiri switched his attention to Nuno when Everton's attempt to re-sign David Moyes failed, with the Scot signing a contract deal with West Ham after leading the Hammers to sixth place last season.
Given Benitez's ties to arch-rivals Liverpool, fan response could be mixed if the Toffees make a move for him. Everton had previously been referred to as a'small club' by the 61-year-old.
